Creating a clay render in Cinema 4D has become a go-to technique for many motion designers, and for good reason. This style effectively showcases a model without the distractions of textures and detailed lighting. In this guide, you will learn how to achieve this popular look, which not only conveys your design work clearly but also renders quickly, making it an essential method for presenting work-in-progress models.

What is a Clay Render?

A clay render is a simplistic and effective way of displaying a 3D model. It typically involves stripping the model of its textures and applying a flat, matte shader that resembles clay. Here are some key reasons why you might want to use this technique:

• Work Status: Perfect for showing clients a model that is still in development without having to worry about intricate details.
• Fast Rendering: Clay renders can be processed quickly, allowing you to focus on modeling and less on lighting or texturing.
• Focus on Form: This technique allows viewers to appreciate the shape and details of the model without distractions.

Getting Started with Cinema 4D

Before diving into the clay render process, ensure that you have a foundational understanding of Cinema 4D. If you’re new to this software, consider exploring comprehensive tutorials available online or courses dedicated to Cinema 4D training.

Once you’re ready with your software set up, follow the steps below to create a clay render.

Step-by-Step Guide to Creating a Clay Render

Step 1: Setup Your Workspace

1. Open Cinema 4D and create a new project.
2. Familiarize yourself with the workspace and set up a new scene.

Step 2: Choose Your Model

Select a model you wish to apply the clay render effect to. For instance, if you have a skateboard model, import it into your scene.

Step 3: Remove Existing Textures

To achieve the clay effect, you’ll want to strip any existing textures from your model ass we focus on the clay material. Instead of deleting them one by one, you can:

• Select the texture tag on your model.
• Right-click and choose “Select Identical Child Tags” to quickly select all textures applied to your model.
• Hit delete, leaving you with a plain 3D object to work with.

Step 4: Create a Clay Material

1. Go to the Material Manager and create a new material.
2. Apply this material to your model. Make sure to base it on a matte color, which mimics the look of clay.
3. Remove any reflection and specular properties from the material to keep it flat and simple.

Step 5: Set Up Your Camera

To replicate the distinct look of traditional clay renders:

• Adjust the camera distance and settings.
• Use a longer lens (around 100mm) to flatten the perspective, minimizing the sense of depth from your model to the camera.

Step 6: Add Background and Lighting

1. Add a Background: Create a simple gradient background that transitions from white in the center to a slightly off-white at the edges. This helps draw focus to your model.
2. Lighting Setup: Using an infinite light, position it to cast soft shadows across your object. Adjust the light’s color to a warmer tone to mimic natural sunlight hitting clay. Ensure that the shadow settings allow for soft shadows, enhancing the overall effect of realism in your render.

Step 7: Tweak Rendering Settings

Once you have your material and lights set up, navigate to the render settings:

• Enable Ambient Occlusion: This effect enhances depth by darkening areas that would naturally receive less light, accentuating the details of your model.
• Adjust the anti-aliasing settings for smoother edges in your render.

Step 8: Render Your Scene

Once you’d made all adjustments, go ahead and render your scene to see the outcome of your clay render.

Step 9: Post-processing Touches

You may need to make adjustments:

• If your model lacks detail or you find the shadows stark, revisit your lighting settings or adjust the brightness of your clay material until you achieve a satisfying look.

Conclusion

The clay render technique in Cinema 4D is an invaluable skill in a motion designer’s toolset. It allows you to present models cleanly, focusing on form and silhouette without the complications of complex textures and lighting. By mastering this process, you can efficiently showcase work-in-progress variants to stakeholders, improving communication and speeding up feedback cycles.
